@RetiredNurse61 π honestly that anxiety-driven approach probably keeps more batteries healthy than any fancy monitoring setup
For what it's worth β I trust my Victron SmartShunt over the BMS SOC...
Curious about the JK active balancer combo here β running a JK standalone on my own pack and it's been solid, but I've heard mixed things about how well it plays with SEPLOS when both are trying...
Yeah, exactly this situation with my cabin setup.
Few things worth knowing for long-term unattended Victron MPPT installs:
Enable absorption/float properly β default settings can be aggressive on...
Had this exact issue last summer with my 100/30. Turned out to be a combination of things worth checking:
Absorption time β mine was set to "adaptive" which calculates time based on the...
Been down a similar road recently β my old semi-flexibles started delaminating after a few summers on the cabin roof, so I swapped them out for a pair of Renogy 175W rigid panels instead.
Worth adding β have you checked whether the Wattcycle uses a Pace BMS or JK BMS internally? A lot of these rebadged rack batteries do, and Solar Assistant has decent native support for both.
On my...
@PartnerAdventure the 70% rule (it's 70% in most UK DNO agreements, not 60% β worth double-checking your G98/G99 paperwork) is honestly a pain when you're mixing inverter brands.
Main issue I've...
@BayFrank genuinely though, have you actually sized the load properly first? Twin 48/15000s is ~30kW inverter capacity β your 30kVA genny will struggle on generator assist if you're not careful...
Had the exact same issue with my 48v cabin setup last year. Turned out my battery voltage sense was off β the MPPT was reading slightly higher than actual due to a dodgy connection on the sense...
@BodgeItAndScarper fully agree with this. My cabin setup is nearly identical β MultiPlus-II with a Cerbo β and it's genuinely baffling that you need VEConfigure on a Windows machine just to tweak...
@JimWilson that's a serious array! With a system that size you're probably looking at the Victron Large System approach β combine panels into higher-voltage strings and use fewer, larger MPPTs...
@FellKev had almost the exact same headache with my cabin setup β 24V Fogstar lithium bank, 12V lead acid starter.
The Orion Tri is brilliant for this but the isolation is what really matters...
Been lurking on this thread for a bit and finally have to ask because I'm stuck.
Running a small off-grid cabin setup β Ecgsolax 6.5kW inverter paired with a 48V Fogstar battery bank.
@VivaraNomad been there. Bought a dodgy 100Ah off eBay for my cabin build β turned up with no BMS documentation, cells were clearly mismatched on capacity testing.
Lesson learned the hard way: if...
@LizStewart worth double-checking your ESS grid setpoint in VRM β I had mine misconfigured for months thinking solar was prioritising properly but it was quietly pulling from the grid more than it...
